The Well

"In the well there is a clear, cold spring
From which one can drink."

This line says: Everything you need is there, in The Well. Knowledge, ability, clarity of mind - it's all available to you. However - this clear, life-sustaining spring will do you no good unless you drink from it.

Potential is just that: potential. You can take some time to do your inner work [Line 4], but the situation will reach a point where you must put these resources to work. Drink deeply. (The Book Of Changes)
